20 species of 10 genera of mites of this family Phytoseiidae were found while studying a species composition on the plants of urban environment Amblyseius andersoni Chant, 1957; Amblyseius rademacheri Dosse, 1958; Neosiulus herbarius Wainstein, 1960; Neoseiulus reductus Wainstein, 1962; Euseius finlandicus, Oudemans, 1915; Kampimodromys aberrans Ouderman, 1930; Dubininellus echinus Wainstein et Arutunjan, 1970; Dubininellus juvenis Wainstein et Arutunjan, 1970; Typhlodromus cotoneastri Wainstein, 1961; Typhlodromus laurae Arutunjan, 1974; Typhloctonus aceri Collyer, 1957; Typhloctonus tiliarum Oudemans, 1930; Paraseiulus incognitus Wainstein et Arutunjan, 1967; Paraseiulus soleiger Ribaga, 1902; Amblydromella (s.str.) caudiglans Scheuten,1959; Amblydromella (s.str.) pirianykae Wainstein, 1972; Amblydromella (s.str.) rhenana Oudemans, 1905; Amblydromella clavata Wainstein, 1972; Amblydromella (Aphanoseius) verrucosa Wainstein, 1972; Galendromus longipilus Nesbitt, 1951. The peculiarities of their spreading in plant associations of Kyiv city, Uman city, Vasylkiv town, Brovary town (Ukraine) which differed from each other by various characteristics (population, area, urbanization degree, etc.) were determined. Total 68 species of plants were examined in the territory of Kyiv city where there were 40 species of trees and shrubs (including 2 types of conifers) and 28 species of herbaceous plants; 16 species of 10 genera of predacious phytoseiid mites were found. 14 species of 8 genera of mites were registered on 25 plant species in the territory of Brovary town (16 species of tree-and-shrub and 9 species of herbaceous plants) in the result of processing of collected materials. 10 species of 7 genera were identified while studying the current state of species diversity of predacious mites of Phytoseiidae family on 26 species of trees and shrubs of green urban plantations within Vasylkiv town. 12 species of 7 genera of Phytoseiidae mites were identified in the result of study of urban plantations in Uman city. Common species at studied areas were the following seven species: A. andersoni, A. rademacheri, E. finlandicus, K. aberrans, T. laurae, T. aceri, T. tiliarum. During the researches the domination index (Di). It was found that spreading of mites was different. Dominant species, subdominant species, subdominant of first order and minor members of species complexes were revealed while analysed the species structure of predacious phytoseiidae mites. E. finlandicus was the dominant in all research plots: Kyiv (Di = 51.63 %), Uman (Di = 60.32 %), Vasylkiv (Di = 15.65 %), Brovary (Di = 33.90 %). K. aberrans (Di = 15.52 %) and E. finlandicus was determined as dominant species n Vasylkiv town. K. aberrans (Di = 2.35 %) and T. aceri (Di = 1.30 %) had the status of subdominant species in research areas. We also have been studied the mite species diversity on the grass and shrubs. We studied the mites on the 93 species of plants where 55 were trees and shrubs (58.9 %) and 38 species were the herbaceous plants (41.1 %).

This study aims to determine the diversity of Herbaceous plants found in the forest Education and Training atMuhammadiyah University of Bengkulu, Central Bengkulu Regency. This research was conducted in January to February 2019 by using the coordinate points LS03040’10” BT 100232’55”. The method used in this study was a direct survey to the research location. The samplewas taken by exploring the research location. The identification of Herbaceous plants samples was did in the laboratory of Muhammadiyah University of Bengkulu. The data obtained was analyzed descriptively. The results of this study were found that it consist of 16 speciesfrom 9 families such as Th eAcanthaceae family, Amaranthaceae, Araceae, Astreaceae, Cleomaceae, Commelinaceae, Marantaceae, Musaceae, Zingiberaceae with a total of 1.052individuals.The species diversity index (H’) at all levels has a value of 1.483 which is a medium categorywith  ecological conditions namely an average temperature is 280C, 86%air humidity, 6.5 soil pH, and 25% soil moisture.

Edge Influence

Abstract Aims Forest edges have been well studied in temperate and tropical forests, but less so in open canopy forests. We investigated edge influence on plant species diversity and soil properties in sparse oak forest fragments. Methods Data were collected along three transects from the edge to the interior of three small (under 10 ha) and three large (over 10 ha) oak forest fragments in Kermanshah province, Iran. We measured herbaceous plants (< 0.5 m in height) and soil attributes at 0 (forest edge), 25, 50, 100 and 150 m. We quantified species diversity using the Shannon index, used rarefaction to compare species richness between two different sizes of fragments and applied non-metric multidimensional scaling ordination to investigate the variation in species composition. We estimated the distance of edge influence using randomization tests. Generalized linear mixed models with post-hoc Tukey's HSD tests were used to assess the effects of distance from edge and fragment size on diversity and soil properties. Important findings We found greater species richness, diversity and evenness at the edge of both small and large fragments, and lower nitrogen and organic carbon at the edge compared to the interior of large fragments, with most changes within 50 m of the edge. Species composition, organic carbon and total nitrogen were significantly different between small and large fragments. Our findings of significant edge influence on herbaceous plants and soil properties in these sparse forests provide a significant contribution to the literature on edges, especially in relation to herbaceous plants.

Selective Preservation

The pioneer diatom study of the Early Weichselian (Valdai) sediments in Lake Ladoga basin was performed. The specifics of the diatom assemblages (co-occurrence of ecologically incompatible taxa, poor species diversity, low diatom concentration and selective preservation) suggest that during the Early Weichselian time intense erosion of previously deposited marine Eemian (Mikulino) sediments prevailed, which resulted in re-deposition of marine diatoms. The sedimentation took place in high-energy environments unfavorable for diatom accumulation and preservation.
